, BEADED STOPPER.

To all whom it may concern.

Be it known that I, ALEXANDER Boo- DANFFY, a subject of the King of Hungary, and aresidcnt of the city of New York, in the county of Kings and State of New York,

have'invented certain new and useful Im-' provements 1n Headed Stoppers, of WlllCll' and a wooden head or flange, the latter hav-v ing made integral therewith a tenon, preferably cylindrical, that is seated in a mortise or recess in the cork. in manufacturing these stoppers, first a cork is blocked from a cork strip and tapered. In the product so obtained is then formed a cylindrical mortise, into which is inserted the tenon of thewood-top or flange, said tenon being before insertion coated with a suitable adhesive, such as for instance glue. These operations are performed on four separate machines, that is on the blocker, the apering machine, the wood-top making machine and the assembling device, necessitating thus at least four operations. In practiceit has been found that thetwo parts of the woodtop cork are apt to separate when thestopper is being withdrawn from the bottle or other container, for instance if the stopper had been inserted into the bottle or other container by force.

One of the objects of the present invention is to provide a headed stopper thatis made of one integral niece, more particularly it is made of artificial or composition cork, or a like substance, whereby the defects of the wood-top stoppers heretofore in use are cffectively obviated and, on the other hand,

the cost of producing the same is greatly re-v ;a bottom plan view of the same; Fig. 3

Specification of Letters Patent. Patgnted N0 3Q, 1%15; Application filed November 19,1914. Serial nastiness;

the invention is illustrated in the accompanying drawings, in which E igure 1 1s a vertical central section taken through a headed stopper made in accord ance with the present invention; Fig. 2 is a vertical central section taken through a mold for forming such stopper; and Fig.

is a front elevation, of a portion of saidmold.

' In the drawings", the numeral 10 indicates a headed stopper, made of artificial or composition cork, or of any other suitable similar material. This stopper comprises a body 11 in the form of a frustrum of a cone that is inverted, or in other words that end thereof which is of smaller diameter forms the base of the same. Upon the top of this tapering body is formed a head or flange 12, which is made integral with the said body. This flange or head,although-shown in the drawingsas being disk-shaped, may be of any configuration to suit the requirements.

For forming this stopper,a mold is use of, for instance the one shown in made rigs. This mold comprises a mold body 13, in which is formed asuitablenumber of cylindrical bores 14. Each of these bores comprises two sections 15 and 16, the section 15 being of a larger diameter than the section 16. In each section 16 is slidably disposed a sleeve 17. pro vided upon its upper end, which projects into the section 15 of the bore, with a flange 18. The upper section 19 of the bore in the sleeve 17 is tapered, and below this tapered section is formed a shoulder 20, on which rests the flange 21 of an ejector 22, that is slidably disposed in the sleeve 17,.and provided upon its'lower end with a head The ejector-22 projects beyond the low *r end of the sleeve 17, the lower end of the latter having a stop 24 for a purpose hereinafter to be described. The fiange'21 of the ejector- 22 constitutes the bottom of the'mold, its

top being formed by a cover 25, to which are attached or with which may be made integral plungers 0r tampers 26, that fit into the sections 15 of the bores 14in the mold body. The lower faces 27 of the plungers or tampers may be shaped to suit the requirements; To

hold the cover 25 upon the mold body, there may be provided suitable clamping devices,

22 are in their lower positions, as shown' 'Hl Fig. 3 of the drawings.

The artificial cork or other suitable composition is then A cured into the mold, the superfluous ma terial wiped off from the top of the mold, the plungers or tampers inserted into the sections 15 of the bores and driven home by applying pressure until the lower face of the cover abuts against the mold body. The hooks 28 are then engaged with the studs 30 on the mold body. The mold is then placed into an oven in which it is subjected to the action of heat for the purpose of setting, coagulating or vulcanizing, as the case may be, the binding material with which the cork or other granules are mixed. The temperature employed varies, of course, according to the nature of thebinding material, and so does also the time" during which the heating action is to be maintained. After heating, the molds are withdrawn from the oven and left to cool. After cooling, the cover of the "mold is removed and, first, the sleeves 17 pushed toward the upper face of the mold as far as the stops 2% on the said sleeves will permit. The ejectors are then forced upward with the result that the finished headed stoppers are removed from the mold.

It will be observed that, inasmuch as the composition cork or other material is packed into the mold, a homogenous body of solid cork or similar material is obtained that lacks the pores, holes and other defects usually to be found in natural cork-wood. In tamping or packing the artificial cork or similar material into the mold, the head 12 of the stopper being formed is subjected to considerably greater pressure than the body 11 thereof, and for this reason, while said body is elastic in the same degree as natural cork-wood, the head formed obtains almost the rigidity of Wood. The headed stopper Copies of this patent may be obtained for The cover formed thus possesses the qualities of the woodtop stoppers heretofore in use, that is to say it comprises an elastic tapered body on that end thereof which is of larger diam-' eter, said body being elastic and said head relatively rigid.

3. A headed stopper made of a suitable composition comprising a body in the shape of a frustum of a cone, and a head made integral therewith and formed on that end thereof which is of larger diameter, said body'being elastic and said head relatively rigid.

4:. A headed stopper comprising an elastic body in the shape of a frustum of a cone, and a disk-shaped flange made integral therewith and formed on-that end thereof which is of larger diameter, said flange bein relatively rigid.

0.1%. headed stopper made of artificial cork or like material and comprising abody in the shape of a frustum of a cone, and a disk-shaped flange made integral therewith and formed on that end thereof which is of larger diameter, said body being elastic and said head relatively rigid.

6. A headed stopper made of a suitable composition comprising, a body in the shape of a frustum of a cone, and a flange made integral therewith and formed on that end thereof which is of larger diameter, said body being elastic and said head relatively rigid.
